Wouldn't it be better to get more reference cards / rigs rather than less cards but AIB versions not only they will cost extra 10-15% to buy but also will consume a lot more power for just 10-20% better mining ?
undervolt and OC anyway if the performance is good. the increased power consumption wont be an issue. even for 250w card

Miners will just buy the AIB cards and run them at reference settings if power consumption really gets out of hand with minor OCs. Also, if the 480s mine well, there will be no "wouldn't it be better to get more reference cards" because all the reference cards have already been bought by other miners.

At any rate, we should be able to agree that the 75 watt limit is entirely artificial. The spec page for a mini-fit jr is 9 amps per pin, for 324 W on a 3-pair connection. Even if pin 2 were to be omitted, the "six pin" would still be rated for up to 216 W if wire gauge and trace size on either side were appropriate. I feel that the 75W limit was a result of some guy at PCI-SIG saying "surely GPUs won't need more than 150 W total."

sorry you can't get that site to load - it is java bug ridden so no surprise. it took me some time to find it as it seems those (actual) specs are hidden for national security or the like. tongue.gif

however yeah, we are in agreement. hope i didn't come off as an ass, i saw a few details you mentioned that i had hoped to . . . "help you" with. not saying you but i've seen some pretty wild theories about PEG power supply.

cheers and thanks for keeping the discussion civil; too rare around here anymore.
Agreed, I'm very big on skepticism and making sure the facts are known. I hate when people go into a discussion with bad information and then further distort the truth. I was always led to believe that pin 2 was not connected (based on lots of sources) but if the PCIe spec says it should be +12V then that is the final word. I'll have to look into the derating some more, but the fact is more than 75/150 watts flow through those connectors all the time without ill effects. The 295x2 is a great example, those only have two 8-pins for something like 500 W of power. I don't think the single 6-pin will be what limits overclockability on this card. I'm guessing thermals and then maybe the VRMs (though a 6+1 phase does seem in line with the needs of the card)

Sorry if this is a nooby question, I've been out of the Cryptocurrency game for quite some time and will spent quite some time researching it.

0.22 eth per day at 30mh/s. About 3usd as of right now.

Oh okay cool, thanks! I think I might throw a GTX 970 and a R9 280 at it.

The RX 480 sounds to be pretty good at mining, it's probably going to be the go-to card for it since it has a fantastic price-point.

Not even close. 0.347 Eth with 290 + 290X OCed 1200/1375 which is no possible in air sustained. Thats ~ 64 MH/s. Thats 5 USD a with current price. That is assuming free electricity, 24/7 operation and degradation of parts. Mining is never worth it in small scale. Only time you make some money is trading at the right time.

Sorry, I meant 0.44 per 60mh\s. (my hashrate with 2x290x @1060/1250)

No it's not. We know it for so long that this card will deliver 390-390x-980 performance.
